MGM Grand, Las Vegas - Juan Manuel Marquez (55-6-1, 40KOs) was sitting like a king at the post-fight press conference on Saturday night. He knocked Manny Pacquiao (54-5-2, 38KOs) out cold in the sixth round of their fourth and likely final battle. Their first fight, in 2004, ended in a twelve round draw, with Pacquiao winning close controversial decisions in 2008 and 2011. Photos by Stacey Verbeek.
